Airline spokesman Charles Hobart said United Airlines Flight 294 was canceled shortly before it was due to leave Phoenix Monday due to a "blockage in the lavatory," the (Cleveland) Plain Dealer reported Wednesday.
"A blockage occurred in the lavatory, which caused several of the lavatories on the airplane to become inoperable," Hobart said. "We realized we would have to cancel the flight in order to fix the aircraft."
United said some customers who were to catch connecting flights in Cleveland were rebooked on different flights, while 71 passengers bound for Cleveland as their final destination were put up in nearby hotels for the night and left Phoenix the following morning on the now clog-free plane.
Passenger Rick Milligan said United workers told passengers there was a diaper clogging the toilet.
"After 6 hours of giving us diaper updates, they finally just canceled the flight," he said.
